I have a whiteboard in my kitchen for everything I need to get done. I generally do a big weekly braindumo then add or remove as I think about them. I also have a notebook in my purse and use notes on my phone for anything I forget to add.
I also have a shared Google calendar with my husband. So that we can co-ordinate schedules/appointments.
Work same thing – whiteboard for my brain dump, notepad for when I am in meetings or I need to pick items to focus on.
